Guest host Kate Burton presents four unusual love stories.  David Galef imagines “My Date with Neanderthal Woman,” read by Giullian Yao Gioiello.   It’s raining old boyfriends and ex-husbands—literally—in Marie-Helene Bertino’s “Edna in Rain,” read by Colby Minifie.  An extra-marital affair becomes a comedy of errors in Sam Ruddick’s “Leak,” read by “Wait Wait…Don’t Tell Me” host Peter Sagal.  And Kathleen Turner performs Isabel Allende’s magical “The Little Heidelberg.”
